In this .prac 1n Figs. el, .5, aand 6, amodification is tice, the operator is relied upon to projpeily:l1 shownin which the clip is provided with aV space the reinforcing rods runningthe same inloop 8" adapted to pass under a longitudinal'. genera-ldirection from one another, and rod 10, a pair of opposed or coactingloops owing'to the character ofthe labor employed 11 adapted to engagethe transverse rod 12 in this work, it frequently occurs that the and anextension or member 13a on one of rodsv are not .equidistantly orproperly theiloops 11 which is provided with a loop spaced andas aresult, `the reinforcement 17 to* iold a transverse rod l2" properly 95.will notbe as eiiicient as desired. To meet spaced from the rod 12 and ahook 1 5 at its these conditions, the present invention con` outer endadapted to pass under athird templates, the provision of clips of wiretransverse rod 14 and an extension .18 which which are adapted at onepoint to be lapped is reverted, as at 19, to form a support for' aroundtwo crossed rods to secure them toholding the reinforcing rods s acedabove a 100 gether, and an extension or extensions on staging.
